• Pay attention to the operation instruction and
fix them close to the battery.
• Work on batteries to be carried out by skilled
personnel only!
• Use protective glasses and clothes when
working on batteries. Pay attention to the
accident prevention
EN 62485-3 and EN 50110-1.
• No smoking!
• Do not expose batteries to naked flames,
glowing embers or sparks, as it may cause the
battery to explode.
• Acid splashes in the eyes or on the skin must
be washed with water. In case of accident
consult a doctor immediately!
• Clothing contaminated by acid should be
washed in water.
Ignoring the operation instructions, repair with non-original parts or using additives for the electrolyte will render the
warranty void.
For batteries according to the ATEX directive 94/9 EC, the instructions for maintaining the appropriate protection class
during operation must be complied with (see relevant certificate).
1. Commissioning filled and charged batteries
For commissioning of unfilled batteries see separate
instructions! The battery should be inspected to ensure
it is in perfect physical condition. The charger cables must
be connected to ensure a good contact, taking care that the
polarity is correct. Otherwise battery, vehicle or charger could
be damaged.
For the assembly of harness cables or in case of the replacement
of a connector the following torque must be applied:

In case the interval between delivery (see manufacturing date
on type plate) and commissioning is longer than 8 weeks or
the electrolyte level sensor is indicating low electrolyte level
(see table point 3.1.1 ), the electrolyte level has to be checked.
If the battery is equipped with a single point water topping up
system (optional), for the removal of the BFS plugs only the
appropriate tool must be used. Otherwise the floats of plugs
may be permanently damaged, which can cause overflow
of the cells. If the electrolyte level is below the top of the
separator, it must first be topped up to this height with
purified water (IEC 62877-1 : 2016). The battery is then charged
as in item 2.2.
The electrolyte should be topped up to the specified level
with purified water.
2. Operation
EN 62485-3 "Traction batteries for industrial trucks" is the
standard which applies to the operation traction batteries in
industrial trucks.

• Risk of explosion and fire, avoid short circuits!
• Caution: Metal parts of the battery are always
live. Do not place tools or other metal objects
on the battery!
• Electrolyte is highly corrosive.
• Batteries and cells are heavy.
• Ensure secure installation! Use only suitable
handling equipment e.g. lifting gear in
accordance with VDI 3616.
• Dangerous electrical voltage!
• Pay attention to the hazards that can be
caused by batteries.
2.1 Discharging
Be sure that all ventilation holes are not sealed or covered.
Electrical connections (e.g. plugs) must only be made or
broken in the open circuit condition. To achieve the optimum
life for the battery, operating discharges of more than 80% of
the rated capacity should be avoided (deep discharge). This
corresponds to an electrolyte specific gravity of 1.14 kg/l at
30°C at the end of the discharge. Discharged batteries must
be recharged immediately and must not be left discharged.
This also applies to partially discharged batteries.
2.2 Charging
Only direct current must be used for charging.
For the Hawker Perfect Plus batteries, procedures in
accordance with EN 41773-1 and EN 41774 are permitted.
Only connect the battery assigned to a charger, suitable
for the size of battery, in order to avoid overloading of the
electric cables and contacts, unacceptable gassing and
the escape of electrolyte from the cells. In the gassing
stage the current limits given in EN 62485-3 must not
be exceeded. If the charger was not purchased together
with the battery it is best to have its suitability checked by
the manufacturers service department. When charging,
proper provision must be made for venting of the charging
gases. Doors, battery container lids and covers of battery
compartments must be opened or removed. During the
charge the battery must be removed from the closed battery
compartment on the truck. The ventilation must comply to
EN 62485-3 standard. The vent plugs should stay on the cells
and remain closed. With the charger switched off connect up
the battery, ensuring that the polarity is correct (positive to
positive, negative to negative). Now switch on the charger.
When charging the temperature of the electrolyte rises by
about 10°C, so charging should only begin if the electrolyte
temperature is below 45°C.
